Durable Perforated Panels For Architectural Acoustic Absorption And Facade Decoration

Shengbo manufactures Alu-Zinc coated perforated panels on high-speed, precision production lines in Tianjin. Combining atmospheric corrosion resistance 2–6 times superior to standard galvanized steel, the ability to withstand over 1,500 hours of salt spray testing without red rust, and a versatile aperture range of 2.5–200 mm, these sheets serve as the material behind roofing substrates, wall panels, ceiling systems, equipment protective guards, and ventilation panels for home appliances.

Shenbo operates a dedicated production facility for the high-speed, precision punching of perforated zn-al-mg coated sheet. As a manufacturer of perforated Zn-Al-Mg panels, the company offers a product that inherently solves the corrosion issue associated with standard hot-dip galvanized sheets—where the exposed steel substrate at the edges of punched holes begins to corrode immediately—thereby eliminating the need for remedial measures such as additional coatings or post-processing.

Shengbo Building Materials is a manufacturer and supplier of perforated sound-absorbing panels based in Tianjin, China, in close proximity to the Port of Tianjin. We produce custom perforated acoustic panels made from materials such as color-coated steel, aluminum, and stainless steel, featuring hole diameters ranging from 2.5 mm to 10 mm and an NRC rating of up to 0.90. All orders undergo a three-stage quality inspection before shipment, and our products come with a warranty of up to 15 years.

Shengbo Industrial is a green enterprise specializing in steel structures for the global market. Its perforated perforated metal mesh are suitable for secondary processing—such as bending, cutting, and coating—and are typically used in conjunction with frameworks or substructures. Common applications include decorative cladding, equipment guards, ventilation screens, and partitions; however, they are not intended for use as standalone roofing panels or load-bearing wall panels.
